Sushi and Sashimi

Sushi and its kissing cousin, sashimi, are the most well-known of Japanese foods. While many people feel uncomfortable with the idea of eating raw fish, this squeamishness disappears after a first encounter with meguro (tuna). Sashimi is just the seafood while sushi can have a variety of other ingredients, along with rice. Traditionally a finger food, sushi is consumed in a single bite.

Western avocado lovers will need to forget about dining on their beloved California rolls while in Tokyo. Unlike many Western foods, this particular type of sushi is considered inferior to Japanese sushi.
